The blog provides a comprehensive guide on migrating relational data to Couchbase, emphasizing the ease of transition and reduced total cost of ownership (TCO) while maintaining existing data structures using scopes and collections. It offers a step-by-step process, starting with setting up a Couchbase environment and creating necessary storage components like buckets, scopes, and collections via the REST API. The guide includes a practical example with a sample database and a script to extract relational data into TSV files, which are then imported into Couchbase using the cbimport tool. It highlights how Couchbase's N1QL query language, compliant with SQL++, allows users to perform familiar SQL-like operations, including JOINs, making the transition from relational databases smoother. The blog encourages further exploration of Couchbase's features, like the Index Advisor service, to optimize data querying and suggests additional resources for those interested in deeper insights into data modeling and the use of scopes and collections.
